While the influence of high-status peers on maladaptive behaviors is well-documented, socialization processes of prosocial behavior through high-status peers remain understudied. This study examined whether adolescents’ prosocial behavior was influenced by the prosocial behavior of the peers they liked and whether this effect was stronger when the peers they liked were also well-liked by their classmates. Three waves of data, six months apart, were collected among Chilean early adolescents who completed peer nominations and ratings at Time 1 (n = 294, Mage = 13.29, SD = 0.62; 55.1% male), Time 2 (n = 282), and Time 3 (n = 275). Longitudinal social network analyses showed that adolescents adopted the prosocial behavior of the classmates they liked - especially if these classmates were well-liked by peers in general. In addition, adolescents low in likeability were more susceptible to this influence than adolescents high in likeability. The influence resulted both in increases and – especially – decreases in prosocial behavior, depending on the level of prosociality of the liked peer. Findings suggest that likeability represents an important aspect of peer status that may be crucial for understanding the significance of peer influence with respect to prosocial behaviors during adolescence.

虽然高地位同伴对适应不良行为的影响已有充分记录，但通过高地位同伴进行的亲社会行为的社会化过程仍然没有得到充分研究。这项研究检验了青少年的亲社会行为是否受到他们喜欢的同龄人的亲社会行为的影响，以及当他们喜欢的同龄人也受到同学的喜爱时，这种影响是否更强。间隔六个月的三波数据在智利青少年中收集，他们在时间 1（ n = 294，Mage = 13.29， SD = 0.62；55.1% 男性）、时间 2（ n = 282）完成同伴提名和评级，和时间 3 ( n = 275)。纵向社交网络分析表明，青少年会采纳他们喜欢的同学的亲社会行为——特别是如果这些同学普遍受到同龄人的喜爱。此外，喜爱度低的青少年比喜爱度高的青少年更容易受到这种影响。这种影响会导致亲社会行为的增加，尤其是亲社会行为的减少，具体取决于所喜欢的同伴的亲社会性水平。研究结果表明，可爱度代表了同伴地位的一个重要方面，对于理解同伴影响对青春期亲社会行为的重要性可能至关重要。预注册：https://osf.io/u4pxm。
